NUT-LOCKING DEVICE.

Application filed August 26, 1918.

To all whom it may concern:

Be it known that I, VILEY J. HALES, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Nut-Locking Devices, of which the following is a specification.

This invention relates to new and useful improvement in a nut locking device.

The principal object of the invention is to provide a device of the character described, whereby fish plates may be securely locked to the rail ends, forming the joint of a railway track.

. Another object of the invention resides in the provision of a locking device, which will lock both the bolts and the nuts employed in securing the fish plates of a railway joint to the rail ends.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1, is a side elevation of a railway joint, showing my improved form of locking means applied thereto.

Fig. 2, is a transverse sectional view, taken on the line 2-2 of Fig. 1.

Fig. 8, is a side view of a form of bolt employed showing the nut in section.

Fig. 4c is a side View of a form of the looking rod employed, and

Fig. 5, is a transverse sectional view thereof, taken on the line 5-5 of Fig. 4:.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numerals 1, 1, refer to railway ties, which extend transversely of the road bed, and are spaced apart, and which are provided to receive the rails. Two rails 3, 3, are shown, whose ends abut, forming the joint 4. On opposite sides of the abutting ends of the rails are the fish plates 5, 5, which fit closely against the webs 6, 6, of said rails and whose lower edges are curved outwardly, to fit over the flanges 7, 7 of the rails. These rails and fish plates are of the usual and well known construction, and they are secured to the ties by means of the usual spikes 8, 8. Passing through each end of the fish plates and the adjacent rail webs Specification of Letters Patent.

are the bolts 9. One end of each bolt is formed into the head 10, and the other end of the bolt is outwardly threaded to receive the nut 11. The inner side of each head has the notch 12, said notches being arranged in alinement and likewise the inner side of each nut is provided with a notch 13.

In forming the joints, the rails are placed on the ties with their adjacent ends abutting together, and the bolts are then passed through the fish plates and rail webs. A locking rod 14 is then seated in the alined notches 12, and the nuts 11, screwed in the opposite ends of the bolts, the locking rod 1a holding the bolts against turning. The nuts 11 are screwed until their notches 13 aline, and the locking rod 15 driven through the notches, and its ends overturned, as shown in Fig. 1. As shown in Figs. 4; and 5, this rod has slightly enlarged sections as 16, said enlarged sections being slotted at 17. These enlarged sections are so spaced apart that when the rods are seated in the notches 12 and 13, the enlarged sections 16 will rest in said notches and the slots 17 are provided so that said enlarged sections will be yieldable, and when the rods are seated in place, said sections will expand against the sides of the notches to hold the rods against lengthwise movement, thus holding the rods securely in place, and making the overturning of their ends unnecessary.

What I claim is:

1. In a device of the character described, the combination with railway rails, whose ends abut of fish plates, arranged on opposite sides of said abutting ends, bolts passing through the fish plates and webs of the rails, one end of each bolt having a head and the opposite end thereof being threaded, nuts secured onto the threaded ends of said bolts, the inner sides of said heads being notched, and the inner sides of the nuts being notched, locking rods seated in the notches, of said heads and nuts, respectively, to lock the bolts and nuts against turning, and means securing said rods against lengthwise movement in said notches.

2. The combination with two railway rails arranged in alinement and having abutting ends of fish plates on opposite sides of said ends whose outer surfaces are plane, bolts passing through said fish plates and the intervening rail webs, one on each side of the rail joint, each bolt having a head on one end and having its other end externally threaded, nuts threaded onto said ends of said bolts, the inner sides of the bolts and nuts having notches arranged in alinement, a locking rod on each side of the plates and seated in the corresponding notches and resting against said plane surfaces, and means securing said rod against lengthwise movement in said notches.

'3. The combination with two railway rails, having'abutting ends of fish plates securedto the rail ends, 011 opposite sides, bolts passing tln'ough the fish plates of each rail and through the rail webs, said bolts being arranged on opposite sides of the plate, a head carried by one end of each bolt, the other end of said bolt being threaded, nuts screwed onto the threaded ends of the bolts, locking rods seated in the respective notches of the heads and nuts to prevent themvfrom turning relative to each other, said rods having expansible sections which fit in the corresponding notches and secure the rods against lengthwise movement in said notches.

In testimony whereof I have signed my name to this specification in the, presence of two subscribing witnesses.
